A method for stabilizing shock waves in channel flow by means of a surge chamber

Stanford E. Neicenaca-tn-2694Jun 1953

In order to stabilize normal shock waves in channel flow against the effect of disturbances originating downstream, a method based on mass removal from the channel by means of a surge chamber was developed and experimentally tested in an intermittent blowdown-type wind tunnel at Cornell University. A theoretical analysis of the flow in a channel shape similar to that used in a typical double-throat supersonic wind tunnel indicated that the mass-removal technique was effective in damping the motion of the normal shock caused by a strong compression pulse originating downstream.
